How Chemical Free Sunscreen Works This non-greasy formula provides broad-spectrum UVA/UVB protection and helps keep skin hydrated without using chemical sunscreen actives like octinoxate and oxybenzone. Instead, titanium dioxide, a naturally-occuring mineral creates a micro-fine barrier on your skin to reflect the sun's harmful rays. Burt's Bees' natural sunscreen is effective immediately upon application and safe for kids. Featured Ingredient Titanium Dioxide: Occurring naturally as the mineral rutile, this substance is used chiefly as a white pigment and as an opacifier. It reflects light, so (when identified as such) can be considered a natural sun block. Benefits of the Burt’s Bees chemical-free sunscreen At Burt’s Bees, they use only natural active ingredients in their sun protecting products. Unlike sunscreens that use synthetic active ingredients, they use titanium dioxide, a naturally occurring mineral. As with all their products, their chemical-free sunscreens are also free of parabens, SLS, petrochemicals and phthalates. A physical sunscreen works by creating a micro-fine barrier—a physical block—that sits on top of the skin. The barrier, created by titanium dioxide, reflects the UVA and UVB rays away from your skin. Once the sunscreen is applied, the physical block goes to work immediately. In contrast, synthetic active ingredients need time to be effective — up to 30 minutes. That’s because chemical sunscreens have to soak into the skin before they begin to work. They do not create a physical barrier to combat the sun’s harmful rays.
